aFe Power BladeRunner 3in Intercooler Tube for 2011-2016 GM Silverado/Sierra 2500/3500 HD (V8-6.6L) 46-20118

Fits 2011-2016 Chevrolet Silverado and GMC Sierra 2500 HD/3500 HD (V8-6.6L).

The aFe Power BladeRunner intercooler tube replaces the restrictive factory charge pipe with a high-flow 3-inch mandrel-bent stainless steel design. Engineered for maximum efficiency, this hot-side tube improves airflow by 67% over the stock component, delivering dyno-proven gains of 16 horsepower and 49 lb-ft of torque. The smoother air transitions help lower Exhaust Gas Temperatures (EGTs) and improve throttle response under load.

Built to handle high-boost diesel applications, this tube features 100% MIG-welded construction and includes heavy-duty 5-ply couplings paired with constant-tension T-bolt clamps for a secure, leak-free seal. The kit includes a specialized bracket to relocate the brake line for proper clearance, ensuring a hassle-free installation using factory mounting points.
